The disclosure herein provides methods, systems, and devices for ventilating the interior of a vehicle with concealed dynamic ventilation system. A concealed dynamic ventilation system and vents thereof can beneficially provide one or more passengers in a vehicle with an increased distribution of air substantially throughout the cabin of a vehicle as compared with traditional vents that are limited to fixed locations with limited capabilities. Further, a concealed dynamic ventilation system can provide aesthetic value by concealing the vents from a passenger's line of sight in a normal seating position behind existing trims of a vehicle.
This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/697,625, filed Sep. 6, 2012, entitled “CONCEALED DYNAMIC VENTILATION SYSTEM,” which is hereby incorporated herein by reference in its entirety.
BACKGROUND1. Field
The embodiments herein relate generally to heating and cooling ventilation (“HVAC”) systems and more particularly to concealed dynamic ventilation systems in vehicles.
2. Description
With the development of new technologies, automobile companies have manufactured cars with various types of vents to provide heating, cooling, and air circulation to passengers to increase passenger comfort in the cabin of the vehicle. These vents typically comprise small, thin, horizontal or vertical flaps that function as air directors to guide the air in the main cabin of the vehicle. Despite improvements in HVAC systems, vents are naturally limited by their size and configuration. In most cases, vents are only able to provide limited quantities of air over a limited range of motion to passengers in the vehicle. With such vents in vehicles, passengers frequently must wait to experience heating or cooling as air exits through the minimal cross sectional area and diffuses throughout the vehicle. Often, poor circulation of air results in the localization of air in particular regions of the vehicle as well. In addition, passengers in the rear of the vehicle may be limited to limited and/or smaller vents in the rear cabin or vents that are located in the front of the cabin on the dashboard to receive ventilation as some vehicles do not provide independent vents for the rear cabin. As a result, passengers in the rear may experience different amounts of air flow as passengers in the front cabin. Further, due to one or more of the shortcomings mentioned above, passengers may increase the level of air flow in the car in an attempt to expedite or otherwise improve the cooling, heating, and/or air circulation. However, this is often accompanied by an increase in the volume of the HVAC system that can present a wholly separate discomfort to the passengers.

For purposes of this summary, certain aspects, advantages, and novel features of the invention are described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any particular embodiment of the invention. Thus, for example, those skilled in the art will recognize that the invention may be embodied or carried out in a manner that achieves one advantage or group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein.
The foregoing and other features, aspects and advantages of the present invention are described in detail below with reference to the drawings of various embodiments, which are intended to illustrate and not to limit the invention. The drawings comprise the following figures in which:
Embodiments of the invention will now be described with reference to the accompanying figures. The terminology used in the description presented herein is not intended to be interpreted in any limited or restrictive manner, simply because it is being utilized in conjunction with a detailed description of certain specific embodiments of the invention. Furthermore, embodiments of the invention may comprise several novel features, no single one of which is solely responsible for its desirable attributes or which is essential to practicing the inventions herein described.
The disclosure herein provides methods, systems, and devices for ventilating the interior of a vehicle with concealed dynamic ventilation system. A concealed dynamic ventilation system can be installed in any vehicle, including but not limited to an automobile, ship, or airplane. A concealed dynamic ventilation system can beneficially provide one or more passengers in a vehicle with an increased distribution of air substantially throughout the cabin of a vehicle as compared with traditional vents that are limited to fixed locations with limited capabilities, such as a dashboard of a vehicle. The increased cross sectional area of one or more vents of a concealed dynamic ventilation system can result in less air turbulence and/or buffeting of the passengers and provide more rapid and even distribution of air throughout the cabin.
In automobiles, vents of traditional HVAC systems are typically located in the front of a cabin on the dashboard, with one or more vents located on a center console, one or more vents located adjacent to a driver cockpit, and/or one or more vents located adjacent to a passenger in the front seat. In some vehicles, car manufacturer designers may provide a rear center console with one or more vents and/or vents under the front seats. There are usually few, if any, vents located on doors or pillars of the vehicle. As a result, passengers in a vehicle are limited by the amount of air that may be distributed via these fixed vents at any one time throughout the car, and passengers frequently must wait to experience heating or cooling as air exits through the minimal cross sectional area and diffuses throughout the vehicle. Often, poor circulation of air results in the localization of air in particular regions of the vehicle.
However, by employing a concealed dynamic ventilation system as described herein, more efficient cooling, heating, and/or air ventilation can be obtained due to vents with larger cross sectional areas and installation throughout the cabin of a vehicle. Because vents in a concealed dynamic ventilation system can comprise wider openings with larger cross sectional areas compared to traditional vents, increased distribution of air flow is possible. Also, because concealed dynamic ventilation system can be installed throughout the cabin of a vehicle and is not confined to locations of vents of traditional HVAC systems, a more even distribution of air is possible as well. At the same time, the strategic configuration of vents of a concealed dynamic ventilation system can even increase cabin space for other components compared to traditional HVAC systems.
Additionally, typical HVAC systems emit considerable levels of undesirable noise throughout the vehicle when the systems are in use. However, by providing a larger cross sectional area through which air can flow a concealed dynamic ventilation system can reduce the level of noise emitted for similar and/or improved ventilation capabilities. The system as a whole can also be more efficient because less force is required to for similar and/or higher levels of air flow as a consequence of the larger cross sectional area of the vents. In traditional HVAC systems, to ensure that a duct in the rear cabin gets air, a secondary fan is generally installed downstream from the main fan to pull air. However, vents of a concealed dynamic ventilation system with larger cross sectional areas can permit air to flow more easily throughout the perimeter of the interior of the vehicle. This can allow a concealed dynamic ventilation system to operate more efficiently with or without a secondary fan. As a result, concealed dynamic ventilation systems can improve fuel consumption levels in vehicles, including hybrid and/or electric vehicles.
Moreover, in modern vehicular design, there is a growing trend to install larger center console display screens. However, the size of the screen is limited by the amount of space that is remaining after allocating adequate space in the center console and adjacent areas in the dashboard for vents of traditional HVAC systems. Concealed dynamic ventilation systems present a solution in response to this industry trend in vehicular design. By reducing the amount of space devoted to vents while maintaining and/or improving the performance of ventilation systems, concealed dynamic ventilation systems can allow for larger console display screens that were not available in conjunction with traditional HVAC systems.
The numerous displays and buttons required in today's vehicles also leads to a great deal of clutter and demand for dashboard space. Concealed dynamic ventilation systems can provide more space and a cleaner aesthetic appearance to today's cluttered dashboards by removing unsightly traditional vents.
Overview
A concealed dynamic ventilation system can generally comprise an elongated opening or vent that can be located in one or more locations throughout the interior cabin of any vehicle. Cooled, heated, and/or unconditioned air can flow from an air source, through the opening and/or vent, and to the interior cabin of a vehicle. In some embodiments, one or more vents of a concealed dynamic ventilation system can be hidden from the line of sight of a passenger(s) in a normal seating position(s) despite their positioning all throughout the cabin interior for better air ventilation. In certain embodiments, the one or more vents are completely hidden and/or concealed from a point of view of a passenger(s). In some embodiments, the one or more vents are partially hidden and/or concealed from a point of view of a passenger(s). In other embodiments, the one or more vents are not hidden and/or concealed.
One or more vents of a concealed dynamic ventilation system can comprise any shape. For example, in some embodiments, one or more vents of a concealed dynamic ventilation system can be substantially linear, angular, curved, parabolic, triangular, rectangular, square, pentagonal, hexagonal, heptagonal, and/or octagonal in shape.
In some embodiments, a trim housing comprising a trim portion conceals a vent of a concealed dynamic ventilation system behind the trim portion. For example, one or more edges of a trim can define one or more boundaries of a vent of a concealed dynamic ventilation system. In certain embodiments, a vent of a concealed dynamic ventilation system is substantially linear in shape along the edges of a trim. The trim can be made of fabric, leather, wood, carbon fiber, alcantera, stone, graphite, alloy, vinyl, different material from the dash, same material as the dash, and/or any other material.
In other embodiments, a vent or opening of a concealed dynamic ventilation system is defined by one or more edges of a surface of a dashboard and/or door panel. The one or more edges of a surface of a dashboard and/or door panel that defines the vent or opening can comprise the same or different material as the rest of the dashboard and/or door panel. Further, the one or more edges of a surface that defines the vent or opening can comprise fabric, leather, wood, carbon fiber, alcantera, stone, graphite, alloy, vinyl and/or any other material
In some embodiments, a first surface of a dashboard or door panel can comprise a lip or area that overlaps a portion of a second surface of the dashboard or door panel, wherein the area between the two surfaces provide a vent, opening, and/or passageway of air in a concealed dynamic ventilation system. Accordingly, a vent(s) of a concealed dynamic ventilation system can be concealed from a line of sight of a passenger(s) in a normal seating position. The first and/or second surface that provides the vent, opening, and/or air passageway can comprise the same and/or different material as the rest of the dashboard and/or door panel. Further, the first and/or second surface can comprise fabric, leather, wood, metal, stone, graphite, alloy, vinyl and/or any other material.
In some embodiments, one or more surfaces that define and/or provide a vent or opening of a concealed dynamic ventilation system can be monolithic and/or contiguous with the rest of the dashboard and/or door panel. However, in other embodiments, the one or more surfaces can comprise a separate layer and/or structure from the rest of the dashboard and/or door panel.
In certain embodiments, one or more features of a concealed dynamic ventilation system or vents thereof can be used alone or in conjunction with traditional HVAC systems, vents thereof, and/or traditional trim configurations to provide improved ventilation within the cabin and/or any other advantages described herein.
Front Cabin
In some embodiments, one or more vents 118 of a concealed dynamic ventilation system or portions thereof can be substantially linear and elongated in shape. For example, in certain embodiments, one or more vents 118 of a concealed dynamic ventilation system can run substantially the length of a dashboard, A-pillar, and/or roof panel. In certain embodiments, one or more vents 118 of a concealed dynamic ventilation system or portions thereof can be circular and/or curved in shape. For example, a circular vent 118 of a concealed dynamic ventilation system can be located within the rims of a steering wheel 110. In certain embodiments, one or more vents 118 of a concealed dynamic ventilation system or portions thereof can be angular and/or curved in shape. For example, a vent 118 of a concealed dynamic ventilation system can be linear, angled, and/or curved in some portions to substantially trace an edge of a dashboard and/or linear or triangular support structures.
As illustrated, one or more vents 118 of a concealed dynamic ventilation system can take up substantially less space compared to vents 104 of traditional HVAC systems. As a result, by utilizing concealed dynamic ventilation systems, more space is freed up in the cabin interior, which can allow for installation of additional or improved components or cleaner dashboard aesthetics. For example, in
In addition, in some embodiments, by positioning one or more vents 118 of a concealed dynamic ventilation system throughout the cabin, as opposed to positioning vents 104 of a traditional HVAC system only at particular positions, air ducts that supply air to the vents 104 can also be located substantially throughout the cabin behind the cabin walls. For example, air ducts can be strategically positioned near or behind one or more electronic components or devices of the vehicle, such as a console display screen 116. In such embodiments, when an HVAC system is operating to cool the cabin, certain air ducts can be configured to deliver cool air to the electronic components or devices, thereby preventing the electronic devices and/or components from overheating. Because of the improved flexibility of positioning vents and ducts in a concealed dynamic ventilation system, air ducts can be generally installed in any location as desired.
Side Door
On the other hand, vehicle doors 200 that comprise one or more vents 118 of a concealed dynamic ventilation system instead of traditional vents 104 can provide increased amounts of air flow due to the larger cross sectional area of the openings. Further, due to the larger cross sectional area of the openings, there is less air resistance. Accordingly, cooling, heating, and/or air circulation through the doors 200 can be more energy efficient with one or more vents 118 of a concealed dynamic ventilation system compared to traditional vents 104.
In some embodiments, the one or more concealed dynamic ventilation system vents 118 may extend substantially the length of a door 200. In other embodiments, the one or more concealed dynamic ventilation system vents 118 may extend a portion of the length of a door 200. The one or more concealed dynamic ventilation system vents 118 may be located in one or more of many directions. For example, the one or more concealed dynamic ventilation system vents 118 may extend horizontally, vertically, or diagonally along the length of a door 200.
In certain embodiments, an air duct is located behind one or more trims 202 or a portion thereof. When the HVAC is off, the air duct can be closed off behind the one or more trims and preventing air from flowing from the air duct to the cabin interior. When the HVAC system is turned on, the one or more trims 202 can move out from a locked position in a substantially horizontal direction towards the interior of the cabin, resulting in a gap between the top and/or bottom edges of the one or more trims 202 and the air duct. Air can flow out of the opening that is created between the edges of the one or more trims 202 and the air duct. For example, air can flow in a substantially upward direction from the gap between the top edge of the one or more trims 202 and the air duct. Similarly, air can flow in a substantially downward direction from the gap between the bottom edge of the one or more trims 202 and the air duct.
Rear Cabin
On the other hand, rear cabins 300 that comprise one or more concealed dynamic ventilation system vents 118 instead of traditional vents 104 can provide increased amounts of air flow due to the larger cross sectional area of the openings. Further, due to the larger cross sectional area of the openings, there is less air resistance. Accordingly, cooling, heating, and/or air circulation in the rear cabin 300 can be more energy efficient with one or more concealed dynamic ventilation system vents 118 compared to traditional vents 104.
In other embodiments, the one or more concealed dynamic ventilation system vents 118 may be located in one or more headrests 308 of a front passenger seat 306. In certain embodiments, the one or more concealed dynamic ventilation system vents 118 may be located in the back support portion of a front passenger seat 306. By providing one or more concealed dynamic ventilation system vents 118 on the headsets 308 and/or back support portion of a front passenger seat 306, air can flow directly at a rear passenger for faster cooling and/or heating, which is not possible by traditional vents and their locations (see
Roof Panel
Generally, automobiles do not comprise vents on the roof panel. However, air right underneath the roof is heated first before air in any other areas due to its direct exposure to the sun. Also, heated air generally rises and gathers near the top portion of a vehicle as well. Accordingly, it can be advantageous to cool the area right beneath the roof panel to more efficiently cool the general cabin interior. As such, in some embodiments, the roof panel comprises one or more concealed and/or not easily detectable dynamic ventilation system vents to directly cool the cabin area beneath the roof panel.
In some embodiments, a passenger of the vehicle can input a desired operating condition of the HVAC system via a user interface 406. For example, a passenger can control a desired temperature, air flow, direction of air flow, one or more vents to be utilized, among others via the user interface 406. In certain embodiments, the inputted control is transmitted to a control module 404. The control module 404 can be configured to control the HVAC system and/or concealed dynamic ventilation system according to the inputted configuration.
In some embodiments, the one or more concealed dynamic ventilation system vents 118 may be located substantially in a trim 102 of a roof panel 114. For example, one or more concealed and/or not easily detectable dynamic ventilation system vents 118 may extend longitudinally along the length of the A-pillar. In certain embodiments, the one or more concealed dynamic ventilation system vents 118 may extend substantially the length of the roof panel 114. In other embodiments, the one or more concealed dynamic ventilation system vents 118 may extend substantially a portion of the length of the roof panel 114.
In some embodiments, the one or more concealed dynamic ventilation system vents 118 may extend in one or more of many directions. For example, the one or more concealed dynamic ventilation system vents 118 may extend substantially horizontally, vertically, diagonally, and/or in a curved configuration.
Air flowing through the one or more concealed dynamic ventilation system vents 118 located in a trim 102 of a roof panel 114 can directly cool and/or heat the area right below the roof panel 114. Also, air can be directed from one or more concealed dynamic ventilation system vents 118 directly towards passengers from above regardless of their seating location. For example, even if a passenger is sitting in a middle seat in the back row, cooled and/or heated air can be directly guided towards that passenger from the roof.
Directing Air—Stationary Vent
Despite the fact that one or more concealed dynamic ventilation system vents can be located throughout the interior of a vehicle cabin and direct air in all directions, it can still be advantageous to be able to further specify the direction of air flow by a passenger. In vents of traditional HVAC systems, louvers coupled to the vents generally direct air flow. In some embodiments, concealed dynamic ventilation system vents can also comprise similar louvers. In other embodiments, concealed dynamic ventilation system vents do not comprise louvers in the traditional sense, but rather comprise modified mechanisms for directing air as described herein.
In some embodiments, the gap between the first surface 502 and second surface 504 can be about 1 inch, about 2 inches, about 3 inches, about 4 inches, about 5 inches, about 6 inches, about 7 inches, about 8 inches, about 9 inches, about 10 inches, or within a range defined by any of the aforementioned values.
Further, in certain embodiments, one or more flaps 506 can be coupled to one or more of the plurality of surfaces or can be located within the vent to direct air. For example, the one or more flaps 506 can be movable and/or rotatable along an axis or pivot point to guide air from the air duct through the vent in a particular direction, including but not limited to up, down, left, right, and/or to a certain degree thereof. In some embodiments, the one or more flaps 506 can be configured to guide air directly to a passenger's body and/or face despite the hidden configuration of the vent. Further, in certain embodiments, the one or more flaps 506 can be configured to substantially stop the flow of air from an air duct through the one or more vents. For example, the one or more flaps 506 can be rotated and/or otherwise moved to substantially block and/or divert an air passageway such that air substantially does not flow out of one or more vents.
Directing Air—Movable Vent
In contrast, in certain embodiments, the vent and/or opening of a concealed dynamic ventilation system itself is configured to move as to guide the air in a particular direction.
In some embodiments, air can flow from an air source located near the front of a vehicle through one or more air ducts and through one or more vents of a concealed dynamic ventilation system to reach the interior cabin of a vehicle. A vent of a concealed dynamic ventilation system defined by a gap between a trim 604 and the remaining surface of the interior cabin can be positioned along any end of a trim 604. For example, a vent of a concealed dynamic ventilation system can be located at a top end, bottom end, proximal end, and/or distal end of a trim 604.
In some embodiments, when in a neutral state, air can be configured to flow from an air duct 602 through both the top and bottom openings of a concealed dynamic ventilation system vent, as shown in
In certain embodiments, the configuration of the trim 604 can be moved and/or altered to allow the air to flow in a particular direction of choice. For example, in the embodiment shown in
Similarly, in the embodiment shown in
In some embodiments, a trim 604 can be configured to rotate to a particular degree of a passenger's choice. Accordingly, a user can choose to increase the air flow out of a particular opening by a certain degree, and decrease the air flow out of the other opening by a certain degree, as well, without completely closing off one of the air flows. By allowing a user to select a degree of rotation of a trim 604, the user can essentially choose the amount of air flow that he or she wishes to be directed in a particular direction. For example, a passenger can choose to open a top opening by about 30 degrees while closing the bottom opening by about 30 degrees.
In certain embodiments, one or more trim openings can be configured to be rotated left and/or right along a substantially vertical axis to direct more and/or less air to the left and/or right. For example, a passenger can choose to rotate a trim along a substantially vertical axis about 30 degrees to the left to close off a left opening about 30 degrees and to open a right opening about 30 degrees. This can allow the passenger to direct more and/or less air towards the window and/or center of the cabin.
The angle of rotation of a trim 604, either along a substantially vertical axis and/or a substantially horizontal axis, can be about 5°, about 10°, about 15°, about 20°, about 25°, about 30°, about 35°, about 40°, about 45°, about 50°, about 55°, about 60°, about 65°, about 70°, about 75°, about 80°, about 85°, or about 90°, or within a range defined by within a range defined by any of the aforementioned values.
In some embodiments, a passenger can simply push either the top, bottom, left, and/or right of a trim 604 to rotate the trim 604. For example, a trim 604 can be configured to rotate by an amount corresponding to the force of a push by a passenger. If a passenger pushes the top of a trim 604 with his or her finger to a certain degree, the trim 604 can rotate to open the bottom opening and close the top opening according to the amount of force exerted by the passenger.
In certain embodiments, one or more vents of a concealed dynamic ventilation system further comprise one or more knobs that are configured to mechanically rotate one or more trim 604. The one or more knobs can comprise a tactile surface. For example, if a passenger rotates a knob by a certain amount, the knob can translate that force of rotation to a trim 604 to rotate the trim 604 by that amount.
In some embodiments, one or more vents of a concealed dynamic ventilation system are coupled to an electromechanical system that is configured to automatically rotate a trim 604 covering a vent. In certain embodiments, the electromechanical system can comprise a user interface and a control module. For example, a passenger can input a command via the user interface to rotate a particular trim 604 by a particular degree. The user interface can further transmit the received command to a control module which can be configured to control the mechanical rotation of that particular trim by that particular angle.
In some embodiments, a trim 604 is configured to rotate around one or more pivot points. For example, in certain embodiments, a trim can be connected to a rod. A trim 604 can be configured to rotate around a pivot point defined by the point of contact between the rod and the interior of a trim. In certain embodiments, a trim 604 can be configured to rotate around a pivot point defined by the opposite end of the rod that is not in contact with the interior surface of the trim.
Targeted Cooling and/or Heating
Generally, heated air accumulates near the top of the cabin interior. Also, due to the proximity and direct exposure to outside heat, air near the top of a cabin interior is heated first, compared to other areas inside the cabin. Accordingly, it can be advantageous to direct conditioned cool air towards the top portion of the cabin interior first, before directing air towards other areas of the cabin. By initially targeting the cooled conditioned air towards the top of the cabin interior, the hottest air within the cabin interior is cooled first, thereby accelerating the cooling process of the cabin interior as a whole. This, in turn, can also save energy and time required for cooling.
Similarly, because cooled air can accumulate near the bottom of a cabin, it can be advantageous to direct heated air towards the bottom portion of the cabin first, before directing heated air towards other areas of the cabin. By initially targeting the heated air towards the bottom of the cabin interior, the coldest air within the cabin interior is heated first, thereby accelerating the heating process of the cabin interior as a whole. This, in turn, can also save energy and time required for heating.
As such, in some embodiments, one or more trims 604 are configured to be rotated or opened in certain directions to allow air to be directed substantially upwards and/or downwards. For example, when in cooling mode, if one or more temperature sensors located within the interior of the cabin detect that the temperature is above a threshold value, then upon turning on the HVAC system, one or more trims 604 can be configured to allow air to be directed in a substantially upward direction. After a certain amount of time and/or once the temperature within the cabin is lowered past a second threshold value, as detected by one or more temperature sensors, the one or more trims 604 can be further reconfigured to direct air to other parts of the cabin. For example, once the interior of the cabin has cooled down beyond a certain value, the one or more trims 604 can rotate from a position similar to that shown in
When in heating mode, if one or more temperature sensors located within the interior of the cabin detect that the temperature is below a threshold value, then upon turning on the HVAC system, one or more trims 604 can be configured to allow air to be directed in a substantially downward direction. After a certain amount of time and/or once the temperature within the cabin is raised past a second threshold value, as detected by one or more temperature sensors, the one or more trims 604 can be further reconfigured to direct air to other parts of the cabin. For example, once the interior of the cabin has warmed up beyond a certain value, the one or more trims 604 can rotate from a position similar to that shown in
Open/Close Mechanism of a Concealed Dynamic Ventilation System
In any ventilation system including the concealed dynamic ventilation system described herein, it can be important to be able to prevent dust and/or other undesirable particles from entering the system through the vents or openings. Accordingly, in some embodiments, one or more vents of a concealed dynamic ventilation system comprise an open/close mechanism. For example, a vent of a concealed dynamic ventilation system can be configured to open only when the HVAC system is turned on. Because air is generally blowing out of the system when the HVAC system is turned on, there is less chance that dust or other particles will enter the vent of a concealed dynamic ventilation system system through the vents and/or openings. On the contrary, when the HVAC system is turned off, a vent of a concealed dynamic ventilation system can be configured to substantially close its openings and/or vents to prevent dust and/or other particles from entering the system. One or more vents of a concealed dynamic ventilation system can comprise any of the open/close mechanisms described herein in conjunction with any of the air directing mechanisms described above.
In some embodiments, the open/close mechanism shown in
In certain embodiments, the open/close mechanism shown in
In some embodiments, a vent of a concealed dynamic ventilation system is configured to open and/or close a particular amount as selected by a passenger. For example, a passenger can choose to open a particular vent by about 0.1 inches, 0.5 inches, and/or 1 inch. By controlling the amount of a particular vent to be open, a passenger can effectively choose the amount of air to be released from a particular vent. In certain embodiments, a passenger can choose to open a particular vent of a concealed dynamic ventilation system by about 0.1 inches, about 0.2 inches, about 0.3 inches, about 0.4 inches, about 0.5 inches, about 0.6 inches, about 0.7 inches, about 0.8 inches, about 0.9 inches, about 1.0 inch, about 1.2 inches, about 1.4 inches, about 1.6 inches, about 1.8 inches, about 2.0 inches, about 2.2 inches, about 2.4 inches, about 2.6 inches, about 2.8 inches, about 3.0 inches, and/or within any range defined by any of the values listed above. Any of the systems described above can be configured to open a particular vent by a width selected by a passenger.
In some embodiments, a trim 604 is configured to move outward and upward to create an opening underneath the trim, but not past the top edge of the duct. In certain embodiments, a trim 604 is configured to also move outward and downward to create an opening above the trim, but not past the bottom edge of the duct. In other embodiments, a trim 604 is configured to only move outward and upward such that the opening and/or vent falls out of the line of sight of a passenger in a normal seating position for aesthetic purposes.
In some embodiments, a passenger can grab a trim 604, for example the top and/or bottom edges thereof, to move the trim 604 in one or more manners described above. In certain embodiments, a trim 604 comprises a tactile surface that can allow a passenger to contact the surface of a trim 604 and move the trim 604 in one or more manners described above.
In certain embodiments, the open/close mechanism described in conjunction with
The open/close mechanism depicted in
When the HVAC system is turned on or when a user turns on this particular opening for air ventilation, the trim or “flipper” 604 can be rotated, as depicted in
In certain embodiments, a trim 604 can be configured to rotate inwards in a downward direction. In some embodiments, a trim 604 can be configured to rotate inwards in an upward direction. In other embodiments, a trim 604 can be configured to rotate inwards in both an upward and downward direction.
In certain embodiments, one or more side surfaces of a rotating trim or “flipper” 604 can comprise one or more louvers 902. The one or more louvers 902 can be configured to direct the air flow in any direction as selected by the user.
Directing Air Within a Duct of a Concealed Dynamic Ventilation System
In order to control the direction of air flow blowing out of a vent, it can be advantageous to be able to control the air flow direction initially within the duct. By controlling the direction of air flow within the duct, the direction of air flow through a vent can be more closely controlled. Accordingly, in some embodiments, a duct of a concealed dynamic ventilation system comprises one or more flaps 1102, 1104 to control the direction of air flow within the duct.
Further, in some embodiments, one or more flaps 1102, 1104 can be configured to accelerate and/or smooth airflow from an air duct 602 through one or more vents. For example, the shape of one or more flaps can comprise a particular curvature to reduce friction of the air flow through the vent in a similar manner as a wing of an airplane. By reducing the friction of air flow via one or more curved flaps, air can more efficiently flow through a vent, thereby decreasing energy consumption and the level of noise.
In some embodiments, the one or more flaps 1102, 1104 can be configured to be controlled electromechanically. An electromechanical system can comprise a user interface and a control module. A passenger can input a command to direct air through a particular vent in a particular direction, for example top, down, left, and/or right. The user interface can transmit the received command to a control module which can be configured to mechanically control one or more flaps 1102, 1104 to block and/or open certain openings to achieve the selected air flow.
In certain embodiments, a passenger can select via the user interface to allow a particular amount of air flow out of a particular opening of a vent. For example, a passenger can select a particular vent to allow roughly 25% of air flow out of a top opening, 25% of air flow out of a bottom opening, 25% of air flow out of a left opening, and 25% of air flow out of a right opening. If a vent only has top and bottom openings or left and right openings or one opening, the user interface can display only the adjustments allowable to a passenger. In some embodiments, a passenger can select a particular opening (left, right, top, and/or bottom) of a particular vent (defined by a particular trim) to allow about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 90%, about 100% of air flow.
Dynamic Thickness of Air Duct
Generally, openings and/or vents located further away from an air source and/or a central fan have weaker air flow, due to the further distance of air travel and/or heightened resistance that hinders air flow. This can result in uneven distribution of air within a cabin. Accordingly, it can be desirable to allow air to more easily reach the vents that are further away, in order to accommodate the otherwise uneven distribution of air. As such, in some embodiments, air ducts of a concealed dynamic ventilation system comprise different thicknesses, depending on the position of the vent that it is configured to deliver air flow to.
Laminar Flow
In vehicles with traditional HVAC systems, in order to achieve fast cooling and/or heating, one must increase the air flow rates to a substantial level, which often produces a loud undesirable noise within the cabin. This noise is mainly due to the fact that the air flow in these traditional HVAC systems is substantially turbulent. Accordingly, in order to decrease the unwanted noise levels while allowing for faster cooling and/or heating, laminar air flow is provided in some embodiments of a concealed dynamic ventilation system.
In certain embodiments, the shape of flaps near one or more vents or where the air exits one or more concealed ducts can help to accelerate and smooth airflow resulting in less cabin turbulence. For example, the shape of one or more flaps can comprise a curvature along direction of air flow to smooth the air flow. This can substantially decrease the degree of turbulence of the air flow in some embodiments.
In certain embodiments, a plurality of thinner straws and/or air pipes can be located inside a larger air duct. As such, air can be forced to travel in a substantially linear direction through each individual thinner air pipe. When air travelling through these individual air pipes reaches a vent or opening into the interior cabin, the air flow can be substantially laminar, thereby substantially decreasing any unwanted noises.
In certain embodiments, the individual thin air pipes within an air duct can be positioned to form a substantially honeycomb-shaped cross-section.
Thermoelectric Device
Referring to
As shown in
With cars going electric and with excess electricity produced at speeds which cannot be used to charge a full battery, electric heating and/or cooling via a peltier type and/or any other suitable thermal exchange device can make use of any excess electricity generated by the car for efficient cooling and/or heating of an interior cabin space of a car. Such a device may provide a compact heating and/or cooling apparatus suitable for placing within various spaces in a car body, including a space within the door 1300. For example, on extremely cold or hot days, such a device can create heating or cooling in a more timely fashion than waiting for the engine to heat up or the AC compressor to deliver chilled refrigerant. Other heating and/or cooling devices may be included in a car door 1300 for providing heated and/or cooled air. In some embodiments, for heating, a more conventional resistive type heating element 1320 may be used. In some embodiments, for cooling, coils containing chilled liquid and/or refrigerant may be used (also represented by 1320).
Undesired heated or cooled air 1316 can be discharged into the door cavity 1304 and/or any other cavity within the car body tolerant of such temperatures and able to contain such heat or cold without discharging the unwanted air 1316 back into the cabin of the vehicle. As described herein, such a cavity could be insulated, such as by an insulating layer 1318. In some embodiments, a door cavity 1304 of the door 1300 can have one or more exhaust vents 1310. The exhaust vent 1310 may be configured to facilitate intake of air from and/or dissipation of air to a space exterior to the door 1300. Radiation of the heat or cold intended for the passenger may be facilitated by an air propulsion device 1306, including a fan, charged ionic plates, any other suitable air propulsion device, and/or combinations thereof. In some embodiments, a door 1300 can include a return air register 1314 located proximate to the air propulsion device 1306 (e.g., as shown in
In some embodiments, air 1308 to be cooled and/or heated by a cooling or heating element may be directed over a thermoelectric device 1302 (e.g., a Peltier type heating and/or cooling plate), a resistive heating element 1320, and/or coils having a coolant 1320, placed within a space within the car door 1300. As described herein, the cooling and/or heating apparatus can be quite compact, and consequently can be placed inside a space of a door (e.g., door 1300) and/or any other space within a body panel of the car. Air may flow via convection and/or an air propulsion device (e.g., a propulsion device 1306), facilitating air flow through the air vent 1312 and into the cabin to cosset the passenger. In some embodiments, air vent 1312 may be concealed by an upper door shell 1324 overlapping an inner door shell 1322.
The thermoelectric device 1302, the resistive heating element 1320, and/or the coils having a coolant 1320, may be contained in other suitable spaces within any other car body portion, aside from a car door 1300. For example, thermoelectric device 1302, the resistive heating element 1320, and/or the coils having a coolant 1320 may be placed (e.g., mounted onto a surface) within a space within a car dashboard, a car roof portion, and/or a car seat.
